Question

If the mass of a material is 45 grams and the volume of the material is 15 cm^3, what would the density of the material be?

Answer 1

first convert to the si units
SI unit for Mass is kilogram and for volume is m^3
45/1000 equals to 0.045kg
15/100 equals to 0.15m^3
Density is equal to mass times volume
D equals to 0.045*0.15
D equals to 0.00675kg/m^3
